Book Description
Since the inauguration of the MRS symposium series on advanced optical processing of materials back in 1990, the number of optical-based techniques applied to process materials and the capabilities of optical systems has continued to expand and improve beyond simple pulsed-laser deposition of thin films. In turn, the scope of materials being investigated has also increased from oxide ceramics to include alloys, polymers and bio-materials. Many of the most exciting areas presented in this interdisciplinary forum include current and future applications in engineering materials at the mesoscopic-to-nanometer scale, optoelectronics, biomaterials, sensors and electronics. Advanced optical processing of materials now includes laser interactions with materials that are specially designed to optimize the beneficial qualities of laser modification. However, femtosecond processing of materials emerged as the dominant theme this year and several papers on this topic are featured. Another hot topic is one connected with biomedical applications--the controlled delivery of drugs to increase their efficacy by coating a fluidized bed of drug powders with biodegradable polymers was realized by conventional pulsed-laser deposition (PLD) and matrix assisted pulsed-laser evaporation (MAPLE) or by microencapsulation.

Book Description
Recent years have witnessed dramatic success in the development of semiconductor materials and related quantum structures for applications in electronics and optoelectronics. Progress has also been made in manufacturable (low cost, high volume) growth and processing of semiconductor materials for such device structures. Novel approaches have been proposed to integrate compound semiconductor devices with conventional silicon processing. This book provides a comprehensive overview of the progress on growth, properties and processing of semiconductor materials and quantum structures, as well to underscore the progress on devices such as transistors, light sources, detectors and modulators. Brought to maturity, these devices will likely see widespread application in infrared imaging, chemical and biological sensing, surveillance, short links, space-based applications, solar cells, high-bandwidth communications, and more. Topics include: electronic devices; Si/Ge devices and technology; zinc oxide and related compounds; emitters, lasers and photovoltaics; nanostructures; innovative materials and devices; detectors; and III-nitride materials and devices.

Book Description
Correlations between quantum efficiencies for photocurrent (phi (x)), emission (phi r), and nonradiative recombination (phi (nr)) are discussed with reference to data from single-crystal, n-type, 100 and 1000 ppm CdS:Te-based photoelectrochemical cells (PECs) employing aqueous sulfide electrolyte. These materials emit while they serve as PEC electrodes. The assumption that the proportionality of phi (r) to phi (nr) is unaffected by potential leads to a simple expression relating phi (x) to phi (r) for monochromatic excitation. Calculated and observed emission data are in reasonable agreement; sources of deviation are discussed. Polychromatic excitation is shown to yield photocurrent and emission intensity which is approximately a weighted average of the values obtained with the constituent monochromatic frequencies. Practical implications of the phi (x) correlation with phi (r) are described, as are related results from other PECs. (Author).

Book Description
Auger electron spectroscopy is rapidly developing into the single most powerful analytical technique in basic and applied science.for investigating the chemical and structural properties of solids. Its ex plosive growth beginning in 1967 was triggered by the development of Auger analyzers capable of de tecting one atom layer of material in a fraction of a second. Continued growth was guaranteed firstly by the commercial availability of apparatus which combined the capabilities of scanning electron mi croscopy and ion-mill depth profiling with Auger analysis, and secondly by the increasing need to know the atomistics of many processes in fundamental research and engineering applications. The expanding use of Auger analysis was accompanied by an increase in the number of publications dealing with it. Because of the developing nature of Auger spectroscopy, the articles have appeared in many different sources covering diverse disciplines, so that it is extremely difficult to discover just what has or has not been subjected to Auger analysis. In this situation, a comprehensive bibliography is obviou-sly useful to those both inside and outside the field. For those in the field, this bibliography should be a wonderful time saver for locating certain references, in researching a particular topic, or when considering various aspects of instrumentation or data analysis. This bibliography not only provides the most complete listing of references pertinent to surface Auger analysis available today, but it is also a basis for extrapolating from past trends to future expectations.
